Chiltern Railways Case Study

Free Train WiFi

Chiltern Railways, train operating company owned by Arriva Trains UK, wanted to deliver a truly connected passenger journey. Having been one of the first train operating companies to introduce free train WiFi in 2011, they were keen to move away from the Carrier model and offer a tailored WiFi experience to enhance their passengers’ journeys.

Continuously Connected Passenger Journey

The development team at WiFi SPARK collaborated with Chiltern Railways and Icomera, the WiFi provider for the trains, to create a totally new product to enable the passengers to enjoy continuous connectivity. (Patent Pending: UK Patent Application Number GB1619398.9) Passengers only have to sign on once to access free WiFi. The WiFi automatically switches from station to train, or train to station for the passengers without them needing to authenticate again.

In addition, as the train approaches the station, the train connectivity is temporarily offloaded onto the station WiFi, ensuring passengers have the best connection available thus reducing the 4G costs. Passengers do not experience a loss of connection.

WiFi SPARK completed an overhaul of 28 stations and 3 depots’ WiFi provision and installed state of the art Ruckus technology to deliver premium digital connectivity. Separate networks were provided for the public and for Chiltern Railways’ corporate and guest access, to ensure security.

Passengers authenticate their free WiFi via email, which ensures that the data collected is robust. Authentication allows passengers to access the free WiFi for 365 days and upon returning, passengers will be greeted with a personalised ‘welcome back’ message. Passengers are then digitally connected continuously through every enabled journey with Chiltern Railways.


WiFi SPARK is the leading specialist in public wireless solutions. The company is the owner and developer of the unique SPARK® platform which delivers the most flexible, feature rich and scalable solution for guest access WiFi on the market today.
